SPECIFICATION forming part of Letters Patent No. .601,841, dated April 5, 1898.

Application filed J une 5, 1895. Serial No. 551,793. (No model.)

T 0 @ZZ whom it may concern:

Be it known that I, SAMUEL N. MCCLEAN, a citizen of the United States, residing at Washington, in the countyof Washington and State of Iowa, have invented certain new and useful Improvements in Breech-Loading Firearms,of which the following is a specification.

My invention relates to improvements in breech-loading firearms 5 and my object is to construct a firearm wherein all the operating parts shall move in and through cam guides or ways, which shall control both the action and combination of the parts.

My invention, when regarded in the entirety of its various parts, may be briefly described as follows:

The frame of the Weapon is formed to receive and distribute the strain of the discharge equally upon all parts of the frame, the side walls of the receiver being alike upon either side of the cartridge receiving and ejecting openings and the bolt having both a forward and a corresponding rear locking device.

The breech-bolt moves in a chamber that is on a line with the bore of the barrel and has both a reciprocating and a rotating movement. The forward end of the breech-bolt is provided with one or more cam-lugs, which engage with corresponding cam-lugs in the receiver when the bolt is rotated to a locked position.

The weapon is actuated by a handle movable beneath the bolt and having a camgroove which partially encircles the bolt and gives it a rotating locking movement.

The shell-extractors are attached to a collar which encircles the bolt and have a reciprocating movement, but do not partake of the bolts rotation. They are actuated to grip and release the cartridge by the diminished depths of the grooves A2.

The magazine is preferably located beneath the barrel and has a rack for maintaining the regular order of its cartridges. This rack forms a separate chamber for each of the cartridges carried in the magazine and is moved in and through a guide which controls its movement. The cartridges are fed from the magazine into the barrel through a fixed path of the movement and are retained in the automatic grip of the operating parts from the time they are placed in the magazine till they have been transferred to the barrel, fired, and

the shell extracted and ejected.

The cartridge-carrier automatically grips the cartridge as it passes into the receiver and automatically releases it as it passes into the barrel and is actuated to perform this function by a reciprocating wedge-shaped cam movable between the gripping-arms of the carrier. The carrier has a vibrating movement between the magazine andbarrel and is actuated to perform this movement by a reciprocating cam-guide preferably located in the handle. This guide has a diamond or double forward end, which construction permits both the carrier and barrel feeding movement of the cartridge.

The cartridge-rack has avseries of notches corresponding to the number of cartridges carried by it, and the handle is provided with a pawl, which engages these notches and actuates the rack to draw the cartridges into the carrier when the handle is reciprocated. These notches are also engaged by an auxiliary dog, which stops and holds the rack. This dog is located in the path'fof the handle and is disengaged from the rack by the handle in the initial part of its rearward movement. v

The tiring-pin is located in a chamber in the breech-bolt and is actuated by a spring which is set by the rearward movement of the bolt. The ring-pin, when in its cocked position, engages with a sear which is located in the path of the handle and is disengaged by the handle to automatically discharge the weapon. supplemental sear which is actuated by a button to discharge the weapon by hand.

The magazine is provided with a slide which disengages the holding-dog from the magazine-rack and acts as a cut-oft' for the magazine. The magazine also has a loadingopening, and when the rack is drawn back into the magazine its chambers can be lilled with cartridges, either singly or from a'case, when the-chambers of the rack pass beneath the opening into the magazine..

The description of my invention, in connection with the accompanying drawings, is as follows:

Figure l is a longitudinal section showing The firing-pin also engages with a p the operating parts assembled. Fig. 2 is a section of the breech-bolt and ring-pin,show ing the mainspring and shellextrators. Fig. 3 is an end view of the same, showing the collar to which the shell-extraetors are attached and the projection on the under side of the collar which acts as a wedge to open the carrier. Fig. i is a partial section of the handle, showing the rack-actuating dog and the stock part of the magazine-rack. Fig. 5 is a cross-section through the handle. Fig. 6 is a plan view of the carrier, showing its gripping-arms. Fig. 7 is a side elevation of the same. Fig. S is a section on the line y y of Fig. 1. Fig. 9 is a section on the line of Fig. 1, showing in cross-section the gripping-arms of the carrier and the guideway for the rack. Fig. 10 is a perspective of that part of the handle which connects with the Ybreech-bolt and contains the cam-groove which rotates the bolt. Fig. 11 is a side elevation of the weapon, showing the side plate and button firing device, together with the opening into the magazine, showing the projections C2 on the sides of the loading-openin g into the magazine. These projections C2 are formed to engage with the cartridge-packet C3, Fig. 1S, and are beveled to cause the cartridge-packet when it is pressed down into position to open and permit the cartridges to roll into place in the magazine as the several chambers in the rack E are drawn past the opening inte the magazine beneath the cartridge-packet when so adjusted. Fig. 12 is a broken view showing a section of the rack E, the dog U, and slide U. Fig. 13 is a plan view of that part of the handle which connects with the breech-bolt, showing the cam-groove in the same, the pin which traverses this groove and is connected with the breech-bolt and in the locking device which engages this pin and locks it in the forward end of the groove to prevent the bolt from being rotated until the locking position is reached. Fig. 14 is an end View of the same. Fig. 15 is a side elevation of the stock part of the magazine-rack `guide. Fig. 16 is a section on the line .e s of Fig. 11 looking toward the butt of the gun, showing the slide which closes the opening into the magazine and the button by which it is actuated to slide forward and open the magazine for the purpose of loading, also the button which connect-s with the cartridge-rack by which the cartridgerack E is drawn forward, causing its several chambers to pass beneath the opening C2 into the magazine. Fig. 17 is a bottom plan View of the breech-bolt, showing that part of the collar which is wedge-shaped and aetuates the gripping-arms of the cartridge-carrier to release the cartridge. Fig. 1S is a detailed view of the cartridge-case. Figs. 19 and 2O are detail illustrations ofthe shell-extractors.

Similar letters refer to like parts throughout the specification.

A is the frame, which is symmetrically formed to resist the recoil and contains the entire chamber in which the breech-bolt reciprocates.

F is the actuating-handle, which has a body and lateral walls. The body of the handle projects through the under side of the weapon and is actuated by the hand to operate the weapon, and its lateral walls rise up into the stock-chamber and engage with the operating parts to actuate the weapon. Located in the lateral walls of the handle are the guides R. These guides R have a double or diamondshaped forward end. For convenience of description 1 have used the letter R to designate the entire track, and R, R2, R3, and R4 are used to designate specific parts of the guide to make clear the barrel and carrierfeeding action of its forward or double end. This guide R has a varying depth t-o cause the pin P2, Fig. 6, of the cartridge-carrier to traverse the double or diamond-shaped part of the groove always in the same direction.

These grooves R are located on the inside ofV the lateral walls of the handle, and the pin P2 of the gripping-arms of the carrier is formed to spring against the bottom of these grooves. That part of the groove designated as R and R3 is of the same depth. The part R2 of this groove diminishes in depth as it approaches the part R3, and the part R4 diminishes in depth as it approaches the part R. Thus the pin P2 when passing from the part R' up through the part R2 is depressed slightly until it reaches the part R3, when it drops into said part, and, passing through that part, it enters the part R4 and is again slightly depressed by the inclination ot' said part until it reaches the part R and drops into it again, the groove thus causing the pin to traverse the double end of the groove always in the direction described. The handle is maintained in position by the lugs F4 (shown in Fig. 5) and the guard G, and the rack-actuating dog S is located (Fig. 4) on the inside of the handle, between the arms F3 of the handle, and has reciprocating movement with the handle to aetuate the rack E.

H is that part of the handle which connects with the breech-bolt. It has a main part and side walls and contains a cam-groove H3,which engages with the breech-bolt J by means of the pin J. The reciprocating movement of the pin J in and through this groove causes a rotating movement of the breech-bolt and accomplishes the locking and unlocking of the same. Located upon the sides of the part H are the ribs H', which are arranged to slide in the grooves A', Fig. 1. This part I1 has a vertical slot H2 in its side and is connected to the handle by the pin F', which moves in said slot.

114 is a dog pivotally retained on the under side of the part II, as seen in Fig. 13. It engages with the piu J, which is attached to the breech-bolt, and is guided in the groove H3 of the part 1I to accomplish the locking movement of the bolt by a forward movement of the part H.

IOO

IIO

H is a projection on the side of the dog H4, which slides in the groove A when the part H is reciprocated. The groove A' curves down, as indicated by the dotted lines in Fig. 11, suficient to cause the dog H4 to be depressed and release the pin J and to allow the continued forward movement of the part H to cause the groove H3 to actuate the pin J to cause the bolt to rotate to a locked position. The dog H4 is pivotally supported in the part H, has a projection H5, which is guided in the cam-groove A, Fig.- 1, and governs the engagement of the part H with the breech-bolt.

The breech-bolt J is a hollow cylinder and has two cam-shaped lugs O, as seen in Fig. 1. These lugs are located on respective opposite sides of the bolt when the bolt is in its forward or locked position, and these lugs are in locked engagement with corresponding lugs O' on the receiver.

The shell-extractors M, Figs. 1, 2, and 3, are attached to a collar N, which encircles the bolt behind the lugs O. The shell-extractors are attached to a collar which is formed with relatively-movable sides adapted to be separated to permit the collar to be inserted around the neck of the bolt between the locking-lugs and the body part thereof, thus allowing the extractors to be applied to a bolt having its bolt-head formed integral with the body of the bolt. The extractors M have a hookshaped forward extremity for engagement with the flange of the cartridge and have a reciprocating movement in and through the guides A2. These guides A2 are located in the side walls of the receiver and extend to a point a little more than the length of the cartridge from the bore of the barrel and may have a diminishing depth, which causes the bottom of the grooves to converge toward the axis of the bore of the barrel. The extractors are constructed to spring against the bottom of these grooves when the breech-bolt is actuated to move forward. The diminished depth of the groove causes the extractors to grip the cartridge and to retain this engagement until the cartridge has been passed into the bore of the barrel, discharged, and the shell fully extracted,when the increased depth of the groove permits the extractors to release the cartridge. These grooves also prevent the extractors from being rotated with the bolt and give them a fixed path of movement.

The firing-pin K has a reciprocating movement in the chamber of the breech-bolt and contains a chamber in which is located the mainspring L and the pin L, which is attached to the receiver and passes through the spring L to retain it in a fixed path of movement. This mainspring L engages with the forward end of the chamber in the firing-pin and is compressed against the rear end of the receiver when the bolt is withdrawn. The forward end of the firing-pin passes through the forward end of the breech-bolt and has a point which encounters the cartridge to diJscharge it. l

The sear W, Fig. 1, is pivotally attached to the left wall of the frame, is actuated by a spring, and engages with the notch K', Fig. 2, in the firing-pin K. This Sear has a'downwardly-projecting arm which extends into the path of the handle and is engaged by the pin F2, Fig. 4, located at the rear end of the handley in the path of ,the sear W, to discharge thev weapon when the handle has reached the limit of its forward movement and the bolt is in the locked position.

The cartridge-carrier P is formed with relatively adjustable lateral sid es which conform to `the shape of the cartridge, the arms of which, as seen in Figs. 1, 6, 7, and 9, are formed to spring against and engage the cartridge,as seen in Fig. 1, and are actuated to release the cartridge by that part of the collar N designated N2, Figs. 3 and 17, which is wedge-shaped at its front end, as seen in Fig. 17, and has a reciprocating movement between'the arms P to cause themto open and release the cartridge when the breech-bolt moves forward to push the cartridge into the barrel. l The cartridge-carrier P has an oscillating movement between the magazine and the barrel and is actuated by the cam-track R of the handle to perform this movement, as hereinafter set forth.

The cartridge-carrier is bell-shaped on the forward end to permit the cartridges to be drawn into it by the action of the handle on the cartridge-rack when the carrier is in position in front of the magazine. The carrier is formed of relatively adjustable sides,which conform to the shape of the cartridge and are actuated to spring against each other. The opposite sides of the carrier are provided with converging cam-faces, as seen in Fig. 6. It

IOO

has a pin P2, as seen in Fig. 6, to engage with the handle and is pivotally connected with the stock, as seen in Fig. 1.

The magazine is preferably located beneath the barrel and is provided with a cartridgerack E, having a separate chamber for each of its cartridges. This rack E is formed of sections relatively hinged together, as shown in Fig. 1, to allow it to traverse the guide D, the sear part of which guide D is curved to conform to the shape of the stock. The pins which form the hinge connection of the rack E project into and move through the grooves in the guide D and control the movement of the rack E. The sections of this rack E are provided in the under sides with notches E and the handle F is provided with a rack-actuating dog S, Fig. 4. This dog S is pivotally retained between the arms F3 of the handle and reciprocat-es with the handle beneath the rack. It has an upwardly-projecting point S2, which engages with'the notches E of the rack, and when the handle is drawn back this engagement causes the rack to move back and IIO draws a cartridge from the magazine into the grip of the carrier. This dog S, when the handle has drawn the cartridge fully into the carrier, encounters a diagonal cam D', Fig. 4, on the under side of the guide D, which cam depresses the dog and causes it to release the rack.

The rack-holding dog U, Figs. l and l2, is pivotally attached to the frame beneath the rack near the forward end of the guard G. It is actuated by a spring and has an upwardlyprojecting end which engages with the notches E' of the rack E and retains the rack in its proper position until the forward movement of the handle brings the dog T, Fig. 4, into engagement with the end of the dog U and causes the dog T to rotate upon its axis, passing over and beyond the lateral part U3 of the dog U to a position sufficiently in front of this dog to complete the handle movement. This dog U has a laterally-projecting lug U3, which has a forwardly-inclined face, as seen in Figs. l and l2. This inclined face is in the path of the rearward movement of the dog T and is engaged by the said dog T to depress the dog U and release the rack at a time when the rack-actuating dog S on the handle engages with the rack to cause it to draw a cartridge from the magazine into the carrier.

The dog U is retained out of engagement with the rack E by the slide or magazine cuto U. This slide U', when actuated, passes beneath the forward end of the dog U and causes its opposite end to be disengaged from the rack,when the rack can be drawn forward into the magazine, and the further movement of this slide or magazine cut-off U will cause the forward end of the dog U to rise up into the path of the rack E and prevent it from passing into the stock far enough to allow the rack-actuating dog S of the handle to engage it, thus cutting the feed of the magazine off and allowing the weapon to be used as a single-loader.

The sear V is connected to the right side wall of the frame and is actuated by the spring V2 and engages with the notch K' of the firing-pin, Fig. 2. This sear V is composed of the parts V and V', and the forward end of the part V' is a lateral projection eX- tending to the exterior to permit the weapon to be discharged by the thumb. This projection is protected from being accidentally discharged by a case V3.

The cartridge-magazine has an opening C', which is preferably located on the left-hand side of the magazine at the forward end of the metallic part of the stock. (See Fig. 11.) This opening is closed by a slide C3, which is moved to open and close the magazine by the pin C5. The side walls of this opening C have projections C2, which engage with the cartridge-case C6 and cause its side walls to be spread apart and allow its cartridges to roll from the case into the chambers of the cartridge-:rack as they pass beneath the case when the rack is withdrawn from the stock into the magazine. The forward end of this opening C is beveled on its inner surface to allow the cartridges to be drawn down into position in the rack without any possibility of clogging. When the magazine has received its full complement of cartridges, the opening C is closed by means of the slide C3, which prevents the cartridges from falling out.

The cartridge-rack E is provided with a pin C5, Fig. 16. This pin C"J projects through the left side wall of the magazine and operates to withdraw the rack from the stock into the magazine.

For convenience of rapid loading I have devised a cartridge-case which is illustrated in Fig. 18. This case is formed on the arc of a circle to conform to the taper and shape of the cartridge and to maintain the cartridges in regular consecutive order and to prevent the anges of the cartridges from impinging behind each other, thus retaining them in' a circular line and preventing them from binding when they are delivered from the case to the magazine.

The operation is as follows: Supposing the parts to be in position as illustrated in Fig. l, and the cartridge being lifted into alinement with the bore of the barrel, the breechbolt being then in its rear position, the mainspring compressed, and the sear V in engagement with the firing-pin, the handle being actuated causes the part I-l to move forward, and the pin J being in engagement with the dog H4 is retained in the forward part of the camgroove H3, thus causing the bolt to move forward in a direct line until it encounters the cartridge and pushes it forward till its forward end has passed into the bore of the barrel and the extractors have passed the flange and been caused to engage with the cartridge by the converging action of the extractorguides A3, the wedge-shaped cam N3 having encountered the converging sides of the gripping-arms of the cartridge-carrier and separated them sufliciently to cause them to release the cartridge, when the cartridge-carrier is actuated-by the handle to descend to a position in front of the magazine by the passage of the pin P3 through the parts R3 and RAk of the groove R, and the further advance of the handle carries the said pin through the part R. In the reverse movement, the pin P2 of the carrier having passed through the part R' of the groove R and coming in contact with the diagonal part R2, it passes through this part as the handle advances and drops into the part R3, thus causing the carrier to ascend to a position in front of the barrel. The further forward movement of the handle causes this pin P3 to move a slight distance in the groove R3 and the bolt J to be advanced in its chamber until the pin H5 of the dog H4 comes in contact with the diagonal part of the groove A', which diagonal part depresses the forward end of the dog H4 and releases the pin J' at a time when the cam- IOO IIO

shaped lugs O have passed to a position slightly in front of the cam-lugs O on the walls of the receiver. The pin J then slides through the cam-shaped groove H3, and in 'so doing imparts a rotating motion to the breechbolt, thus causing the cartridge to be forced home by the cam action of the cam sides of the lugs O and O and the camaction of the cam-groove H3. The handle having advanced at this time and brought the pin F2 into contact with the downwardly-projecting arm of the sear WV and disengaged it from the firingpin discharges the weapon.

The loading action is as follows: The parts being in the forward or discharged position, as above described, the dog T of the handle (see Fig. 4) is in advance of the rear end U3 of the dog U, and this dog U is in engagement with a notch of the rack E. The dog S is then in advance of the succeeding notch in the rack. The initial part of the rearward movement of the handle brings the dog T into engagement with the cam-face U3 of the dog U and disengages the dog from the rack. The dog S at this time engages with the succeeding notch in the rack E to move the rack and draw a cartridge into the grip of the carrier. This rearward movement of the handle causes the pin J' to traverse the groove H3 in the part H, and the cam action of this groove rotates and unlocks the bolt. The further rearward movement of the handle causes the bolt to be withdrawn and the rack E to draw a cartridge fully out of the magazine and into the grip of the carrier, at which time the dog S encounters the cam D on the under side of the rack E, as seen in Figs. 4 and 15, which cam D depresses the dog S and releases it from the rack E. At a time when the pin P2 of the cartridge-carrier has traversed the part R of the groove R and has entered the cam part R2 the cam action of the part R2 will cause the further rearward movement of the handle to lift the cartridges into line with the bore of the barrel.

The magazine-loading action is as follows, the parts being in the position illustrated in Fig. l and the magazine empty, the rack E having passed back into the stock-chamber to deliver the last cartridge to the carrier: The magazine cut-o U', Fig. l2, is slid under the end of the dog U, causing it to release the cartridge-rack E, the dog S being held out of engagement with the rack by the action of the cam D' on the under side of the rack. .The rack being then released from the action of both dogs is free to be drawn forward by the pin C5, projecting through a slot in the side of the magazine, as seen in Fig. 16. The suc'- cessive chambers of the rack may be filled either singly by the hand or from a case as the rack is withdrawn from the stock into the magazine and its successive chambers pass beneath the opening, thus allowing the cartridges to roll into position in the magazine. The forward end of this opening C' is beveled to cause the cartridges to be drawn into position in the magazine and to prevent the for? with the rack E and projects out through a' slot in the stock to permit the rack to be withdrawn by means of this pin.

For convenience of rapid loading-I have devised a cartridge-case which is formed on-the are of a circle and conforms to the taper and contour of the cartridge to retain the cartridges in regular order and to prevent the iange of the cartridges from impinging behind each other and to cause the flanges to remain in regular consecutive order, thus preventing them from clogging when they pass from the case'into the magazine. The opening C' in the magazine is provided with projections C2, which are located on the sides of the opening and are formed to engage with the sides of the case and cause the side walls of the'case to spread apart and release the cartridges when the case is depressed into the opening to permit the cartridges to roll from the case into the magazine.
